UNITEDY STATES GEORGE H. GILMAN, OF BELMONT, MASSACHUSETTS.

Application filed March 2S, 1921.

My invention relates to winches and particularly but not exclusively to a portable capstan for use in mines.

My invention will be best understood from 5' the accompanying drawings and following lll ln the drawings Figure l is a central sectional elevation of the submitted embodiment of my invention; Figs. 2, 3, 4, 5 and 6 respectively are sections on the lines 2-2, 33, 4 4, 5-5 and 6-6 of Fig. l; and

Figs. 7, 8 and 9 respectively are sections on the lines 77, 8-8 and 9 9 of Fig. 3. In general, the submitted embodiment of my invention comprises a drum, its support 'i' having means for attachment to a mine column and fluid operated mechanism for turning the drum.

Referring to the drawings, I have shown a drum l and for supporting it a pillar 3 *'"3 having at its lower end the substantially frusto-oonical projection 4 for engagement with an attachment 5 for securing it to a mine column or like support 6, the pillar being bored out to provide a cavity 7 affording` a chamber for lubricant for the machine.

Adjacent the lower end of the pillar is a flange 9 which supports the motor casing l1, the latter having a peripheral 'wall 13 and being closed by a diaphragm l5.

The motor as shown comprises a dislclilre rotor 17 cooperating with rotary abutments 19 of similar shape, the rotor being pro-vided with a. series of gear teeth 2l, the faces of which fit the interior surface ofthe peripheral wall of the motor casing, while the rotary abutments which fit other portions of the same surface are cut away to form the recesses 23 for meshing with these teeth. rlhe rotor and abutments are so formed that when the teeth have moved out of mesh with the recesses the cylindrical surfaces of the rotor and abutments are in contact. The upper and lower surfaces. of the rotor and abutment-s in a fluid tight manner fit the under surface of the diapliragm l5 and the interior bottom surface of the motor casing.

Motive fluid is supplied the mot-or through a suitable intake connection 2l', and herein the motor is controlled by the combined reversing and throttle valve 27 which I provide with an operating handle 98. This Serial No. 455,927.

valve which is generally cylindrical in shape is provided with the closed-ended axial bore 29 and the spaced passages 3l and 33 placing the bore in c nnmunication with the eX- terior surface of the valve, while in the same transverse planes as the passages 31 and respectively are the arcuate passages 35 and 37 formed on the exterior surface of the valve, and the ports 36 and 38 formed in the wall of the valve casing for placing the interior thereof in communication with the atmosphere. In the bottom portion of the motor casing l form passages 39 and 4l opening into the valve casing and adapted to be placed in communication with the atmosphere or withthe motive fluid supply by means of the valve 27, in such manner that when the passage 39 is connected tov the atmosphere, the passage 4l is connected to the motive fluid supply and-vice versa. As shown by Figs. 3, 7, 8 and 9, the passage 39 is supplied with motive fluid through the valve passage while the passage 4l is placed in communication with the atmosphere by way of the arcuate groove 35 and port 36. If the valve is turned counterclockwise from the position shown by Fig. 7, the supply of motive fluid to the passage 39 will be throttled, and if the turning is continued until the passage 33 is moved out of communication with the passage 39, the supply of motive fluid to the passage will be interrupted and if, from this position, it is turned still farther, the passage 39 willl be connected to the atmosphere by means of the arcuate passage 3l' and port 36, while the passage 41 will be supplied with motive fluid by means of the passage 3l of the valve, which will act to drive the motor in the di` rection opposite to that in which it is driven with the valve in the position shown by the drawings.

rlfhe passage 4l above referred to is provided with the branches 43 and 45 which respectively terminate in ports 47 and 49 opening into the motor casingl adjacent the places of intersection of the rotor 17 with the abutments 19. Similarly, the passage 39 branches into the passages 5l and 53. respectively terminating in ports and 57 which are located at the sides of the intersections opposite the ports 47 and 49. ln Ihe position of the parts shown, motive fluid entering the motor casing through the ports 55 and 57 acts to exert pressure on the abutments and teeth 2l in mesh therewith, thus llo causing rotation ot these parts, while after the teeth have moved out of mesh with the abutments, and while the latter continue to act as abutments to enable the motive fluid 'acting on the teeth to move the rotor, the abutments are rotated by means hereinafter described to cause each tooth consecutively to engage one of the recesses in the side rotors. rlhe motive luid supplied through the port L17 is exhausted through the port 55, and similarly the motive tluid admitted through the port 19 is exhausted through the port 57.

Surrounding` the pillar adjacent the motor is shown a roller bearing 59 for the sleeve 61 and to the latter is rigidly secured the rotor ot the motor by means of a key (53, This sleeve extends through a suitable opening in the diaphragm and supports the pinion carrier 65 of an epicyelic reduction gear ot the planetary type. On the exterior surface of the carrier is formed a series of gear teeth 67 in mesh with pinions GS) secured by means of suitable keys 71 to shaifts TS, the latter being integrally connected with the abutments. The series of gear teeth G7 and those ot the pinion 69 are et such number as to keep the abutments in proper rotative relation with the rotor. The shafts 73 are supported in roller bearings 75 and 77, the latter l eing` supported in the sleeve 'T9 provided with a flange 81, which projects into the motor casing and is received by the cutaway portion 83 of the diaphragm. ln this way, as thel sleeve tightly lits the bore 85 formed in the diaphragm, it together with the flange 81 serves to dowel the diaphr gm to the motor easing. Supported by the diaphragm 15 is a gear casing member Se, having projections 86 receiving the roller earings 75 for the shafts 73. For holding the gear casing member, the diaphragm 15 and the motor casing 11 in assembled relation to each other and to the 'flange 9, l have shown the bolts 88.

t will be observed that both the rotor and abutments act to 'drive the carrier G5 and it desired l may omit the connection between the abutments and the carrier when other means are employed for causing` the rotor and abutments or the motor to revolve at proper relative speeds of rotation.

As illustrated by Figs. 1 and t, adjacent the lower portion et the carrier is a fixed annular series oi' gear teeth 87 formed on the dish 89 which is secured to the pillar by means of the hey 91, and adjacent the opposite end of the carrier rotatably supported on the pillar is the gear 92 ai'ording a series oi teeth 93. On the carrier 65 in parallel relation to the pillar is secured a pair of diametrically oppositely located spindles 95 on which are rotatably mounted sleeves 97 carrying` an annular series of gear teeth 99 meshing with the serias` Q3 and a series 101 meshingl with the fixed series 87. rEhe series 101 and the series 87 in mesh therewith are respectively oit such pitch diameter that they form a gear set oi slightlyY dillierent ratio than the gear set a'tii'orded by the 70 annular series ot teeth 0E) in mesh with the series 93. ln this way, when the motor is in operation, the annula` series ot gear 'teeth 101 is rolled around the series Si' which causes the series 09 to rotate the series 011 75 at a speed much less th aa that ot the rotor.

compa i rhis construction provides a 1 n a chine by reason ot the fac power lor operating the il cured by a high sgced i l which tor a given outputi 'eversely proportional to its speed. l erablj.' the rai io oi gear reduction is sulicicntl;v great enough to provide that when the supply oi" inowc lluid to the motor is interrupted the dri will be unable to turn, owing to the im sibility o1- it drivingl the gearing. and in this way it will be noted a self-leciti,.I.` lduction gear eonnectiiip; the motor and d is secured. l have found that this conti. is satisfactorily provided ttor by ilormi the series 90 and 93 respectively ot l'ourtcer: and thirtyfliour 7gg-pitch teeth and the series 101 and 87 respectively of fourteen and thirty-two i-pitch teeth. J5

ln the present example of mv7 invention, to permit the 'drum to rotate i ependcntly et the gearing, the gear is capable oi. longitudinal movement relative to the pillar and carries a series ot spaced jaws 1055 Wl adapted to mesh with the spaced jans 105 carried by the drum, thus forming a disengageable clutch connection between the lat-- ter and the gear. The gear 92 is termed with an annular groove 10's", which en f 105 the lugs 109 integrally formed on the of the pair of clutch actuating shipper ro 111. For receiving the snippet' rods, the pillar is provided with the slots 113 which are formed on diametricalli.v opposite siifiei; of the surface ot the pillar and extend to adjacent the outer end thereot", where the shait is cut away to term the end slot 115 for receiving the shipper operating block 117. For securing the rods to the block, the 115 end portions ont the tornier are provided with the projections 11I littingl into end sli 121 ot the block and are secured to the blo by means ot pins 128. rihe blocl: is provided with a stem 125. to which is secured 12" the. operating handle 127.

ln the present construction, for holding the clutch in its engaged and disengaged positions, the upper portion of the pillar is provided vith a bore 1211 at opposite end L portions of which are placed plungers and between which is located the compression spring 128 acting to force the plungers outwardly. Each shipper red is provided with a pair of depressions 130, one of which is engaged by the pins in the position oi the shippers in which the clutch is engaged and the other in the position in which it is disengaged.

As illustrated, to provide a bearing tor the drum, over the end ot' the pillar is placed the sleeve 129 and for holding the drum in place l provide the cap 131 secured to the pillar by suitable screws 133, the cap being of diameter greater than the pillar and having a thrust surface 1,35 for the end bearing 137 of the drum.

'lhe lower portion of the drum is provided with a brake flange 139, around which placed the brake strap 14.1. For operating the brake, the strap is secured at opposite ends to nuts 143 and 145 respectively engaging the right and lett hand screw threads lformed on opposite ends ci the bolt 1&7'. Providing a bearing surface for the bolt is a pair ot spaced lugs 149 carried by the gear casing member 84, While longitudinal movement of the bolt is prevented by a collar 151 located between the opposed surfaces ot' the lugs and secured to the bolt by means ot a pin 153. A handle 155 is provided lor operating the brake. The brake liangc and lower por ion ot the drum serve to form part of the gear casing. F or orniing a tight joint between the stationary gear casing member Se and the brake flange, the end of the latter is caused to bear against the packing 156 carried by the adjacent part ot the member Se of the casing.

For lubricating the machine, the drum is provided with an interior cavity 157 adapted to be filled with grease through the plug 159, While leading trom the oil reservoir i' ci the pillar are suitable passages 161 leading to the gear case and passages 163 leading lo the bearing for the carrier 65. The motor is lubricated by lubricant conveyed by suitable passages 165, in communication with the bearing ot the gear carrier, the passage 165 communicating with the top and bottom surfaces o'l the central rotor by means oi: passages 167.
